HHUMIDIFIER.

SPECIFICATION forming part of Letters Patent No. 607,970, dated July 26, 1898.

7 Application filed August 7,1897. Serial No. 647,477. (No model.)

To all whom it may concern:

Be it known that I, RICHARD G. ULBRICI-I, of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Humidifiers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention is a humidifier or drosophore,

to being an improvement onmy previous in vention disclosed in United States Letters Patent No. 572,780, the object of my present invention being to increase the spraying ca-' pacity of the humidifier and to decrease the waste of the liquid thereby.

The details of my invention will be pointed out in the following description and the invention will be defined in the appended claims, reference being had to the accomzo panying drawings, illustrative of a preferred embodiment of my invention.

In the drawings, Figure l is a vertical sec-a 3 5 pipe b controlled by a valve b operated by a transverse arm 19 all as disclosed in my before-mentioned patent or of any other usual -or preferred form.

In my above-mentioned patent the lower and upper parts of the humidifier were connected by a cylindrical case having smooth walls. According to my present invention, however, I provide a case 0, having various angularities, said case being heroin shown as .45 vertically corrugated by similar corrugations 0, extending from the bottom to the top thereof. The effect of these angularities or corrugations is that when the umbellical spray from the nozzle 11 strikes the walls of thecase o it is not only deflected downwardly, as in my patented device, but it is separated by the inwardly-projecting ridges of the angular portions and deflected sidewise, as well as laterally, and the various portions thereof are given a multitude of directions, the spray being separated and commingled to a degree hitherto unapproached. The result is that a large volume of spray in absolute suspension is driven forward, commingled with the air, which is sucked in thereby at the top of the apparatus in the direction of the arrows to so and is driven forward and outward in the direction of the arrows 3 in a superior manner. Also by reason of the angular surfaces against which thespray impinges as it is driven from the spray-nozzle there is a much larger volume of air drawn in at the upper end of the humidifier.

I do not restrict myself to the curved or undulating corrugations c c which I have shown, inasmuch as various other forms of angular surfaces may be substituted therefor, the object being to separate and commingle the spray without condensing it or causing it to form in streams to trickle down 7 5 the case.

In order to isolate the angular or corru gated surface which receives the spray, and thereby overcome the sweating or condensing which would otherwise take place on the outside of the case, I make said surface separate from and place it within the case, as shown at 0 Fig. 3.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A humidifier apparatus having a spray ing device at its upper end and a spray-outlet at its lower end, combined with a casing between said spraying device and outlet, said casin g being vertically corrugated on its inner surface against which the spray may impinge, substantially as described.

2. A humidifier apparatus having a spraying device, a case and an outlet, combined with a surface between said spraying device and outlet against which the spray from the name to this specification in the presence of former is driven, said surface presenting to two subscribing Witnesses.

the spray a series of vertical corrugations,

formed on a separate plate secured within Witnesses 5 the case of the apparatus as and for the purpose set forth.

In testimony whereof I have signed my RICHARD O. ULBRICH.
